Hi,I have approx 300 movies and the majority of them playback fine. However, a number of them stop playback 20 -30 minutes (actually seems to consistently be at 27min 30 secs) into the movie with the message "Playback Not Available". All files are MP4 format.

On my 40" Samsung TV there is no such problem.

There are no updates available for the Sony and I am running Serviio 1.9.
